Error Codes and Descriptions
³
ER: error code displayed until you press a key.
³
WR: warning code displayed for 3 seconds, then unit returns to normal.
[1-port models] In
Pass/Fail mode, only the
battery charge and the
auto-off indicators are
displayed.
You selected ONT
(1310 nm), but this signal
has been deactivated in
the current threshold set
(see
Selecting a Threshold
Set
on page 11).
[1-port models]
Impossible to see the
current wavelength(s) and
the corresponding LED(s)
is (are) off.
The signal is deactivated
(see
Selecting a Threshold
Set
on page 11).
Reactivate the signal (see
Configuring Thresholds
and Correction Factors
on
page 9).
[2-port models] In
Pass/Fail mode,
Impossible to see all
wavelengths and some of
the LEDs are off.
At least one signal is
deactivated (see

Description
Solution
LIGH
Light detected while nulling offsets.
Nulling is not performed.
Correctly place protective cap on
ports, then retry. If the problem
persists, contact EXFO.
ER 12/16 Threshold values are not usable
(corruption problem).
Would occur:
³
during unit initialization
³
after threshold verification (see
Verifying Thresholds
on page 21)
³
after threshold set selection
Download new threshold sets to
your unit. For more information,
see
Configuring Thresholds and
Correction Factors
on page 9.
ER 13 EEPROM corrupted (would occur
during unit initialization).
Unit must be recalibrated.
Contact EXFO.
